EISA Basics
EISA (Public Law 110-140) was signed by President Bush on December 19, 2007 and will become effective
on December 19, 2010.
Beginning on December 19, 2010, motor manufacturers may not build motors with a lower nameplate
efficiency than EISA allows. EISA applies to both NEMA frame motors and the equivalent IEC frame motor.
Motors that are built before December 19, 2010 but are held in inventory or are in transit can be sold,
this deadline applies only to build dates.
General Overview of Levels

General Purpose NEMA & IEC motors that today need to meet EPAct efficiency, will need to
meet the NEMA Premium® efficiency levels (Table 12-12) beginning on December 19, 2010

General Purpose NEMA & IEC motors that were exempt from EPAct because of voltage,
mounting, etc. will need to meet EPAct efficiency (Table 12-11) beginning on December 19, 2010

NEMA & IEC motors that are not considered “General Purpose” (i.e., motors that cannot be used
in most applications, such as special shafts, blowers or nonstandard frequencies, nonstandard
volts/Hz) remain exempt from EISA regulations for efficiency.

Specific EISA Rules – Step 1
Start:
If motor has one (or more) of these features, it is exempt and can be Standard Efficiency
Horsepower less than 1hp or higher than 501hp
Voltage 601 v or higher
Single phase
Frequencies other than 60Hz or 60/50Hz
Design D and Ultra High Slip (UHS) motors
10 Pole and higher pole count
Encapsulated windings
Frame sizes NEMA 56 (IEC 80) and smaller
Non-NEMA Base or Feet
Thrust Bearings
Sleeve Bearings
Non-NEMA (custom) flange / bracket / endshield
Non-standard shaft dimensions (non-NEMA)
Motors for Inverter Use Only (with labels and nameplate)
Brake (installed, not provisions only)
Integral Gear Motor
Saw Arbor
TENV, TEBC, DPFV
TEAO or Open Air Over (DPAO, OPAO)
Non-Continuous / Intermittent (must have time rating, ex: 30 min)
Phase converters
Induction generators
Motors rated & labeled "Inverter Only"
Multispeed
If it does not have any of the
features above, go to next slide
Note: NEMA frames and IEC equivalents are included in the categories above, use features to determine efficiency

Specific EISA Rules – Step 2
Step 2:
If motor does not have any features from the Standard Efficiency section but does have one or more of the
following features, it must meet EPACT (Table 12-11)
201-500hp
Voltages that are not capable of operating at 230v or 460v
Design C
must meet Table 12-11. This means:
8 Pole
Voltage 208v and lower (at 60Hz)
NEMA U or US shaft
Voltage 255v through 416v (at 60Hz)
Footless or Round body
Voltage 510v through 600v (at 60Hz)
Close Coupled Pump
Vertical Normal Thrust
Firepump
If the motor does not have any features from the Standard Efficiency section on the previous slide
and
does not have any features from the EPACT section above, it must meet NEMA Premium (Table 12-12)
Note: NEMA frames and IEC equivalents are included in the categories above, use features to determine efficiency

208v, 208-230v, 208-230/460v
Motors that would need to meet NEMA Premium because they are otherwise General Purpose
A spread voltage rating of 208-230v would require compliance to NEMA Premium (Table 12-12) at 230v and
compliance with EPACT efficiency (Table 12-11) at 208v
A spread voltage rating of 208-230/460v would require compliance to NEMA Premium (Table 12-12) at 230v
and460v and compliance with EPACT efficiency (Table 12-11) at 208v
If the design doesn't comply with the 12-11 levels at 208 volt then, it would be acceptable to use "Operational at
208 volt at ## Max. Amps" on the blank line of the nameplate.
Motors that would need to meet EPACT because of mounting or other features
A spread voltage rating of 208-230v would require compliance to EPACT efficiency (Table 12-11) at both 208v and
230v
A spread voltage rating of 208-230/460v would require compliance to EPACT efficiency (Table 12-11) at 208v,
230v and 460v.

Examples of EISA Rules
Example #1:
Motor ABC is an EPACT motor (12-11) with rating 100hp 230/460v, 60Hz, 405T 1800rpm, TEFC,
standard bracket, horizontal, rigid base.
Beginning on December 19, 2010 it can no longer be sold because it is a General Purpose NE MA motor
and will not meet the efficiency requirements under EISA.
EISA requires that this model must meet NEMA Premium efficiency standards. Increasing the
efficiency of this motor would require a design change.
Example #2:
Motor XYZ is the same as ABC except it has space heaters and a special 13.75” shaft extension.
The special shaft extension makes motor XYZ exempt from the EISA requirements, therefore, it can
continue to be purchased after December 19, 2010 without a design change or a substitute motor.

Why Should I Upgrade?
If my older, less efficient motor fails, why should I upgrade an Exempt motor to NEMA
Premium instead of rewinding the old motor?
Higher efficiency motors:
1) Reduce the operating costs and less stress on utilities, supporting Green initiatives.
2) Generally operate at a lower temperature and for every 10°C reduction in operating
temperature, insulation life doubles.
3) Are generally quieter (smaller fans).
4) Have lower vibration with lower bearing temperatures for longer bearing life.
5) Earn a rebate.
Comparison of Operating Cost:
Example: 100hp 1800rpm ODP motor
Over a 20 year life
this is $18,600
Operating 24 hrs/day, 240 days/year at a cost of $0.08 per kW-hr
Standard efficiency motor with 93% versus NEMA Premium motor with 95.4%
Standard efficiency motor uses $36,963 worth of electricity per year to operate
NEMA Premium motor uses $36,033 worth of electricity per year to operate
In addition to direct energy cost savings, maintenance and downtime will be reduced.

Worldwide Energy Standards
NO LEGISLATION by IEC - - Voluntary Compliance
2/1518/FDIS document issued in Sept 2008 defines levels for IE1, IE2, IE3
IE4 is not defined but is reserved for Super Premium
50Hz
IE1 is based upon EFF2, not a direct match
IE2 is based upon EFF1, not a direct match
IE4
IE3 is based upon 15% to 20% lower losses than IE2
NEMA Table 12-14 for 50Hz was revised in 2009 to match IE3
60Hz
IE3
IE2
IE1 60Hz is equal to Brazil’s level
IE2 60Hz is the same as EPACT
IE3 60Hz is the same as NEMA Premium
IE1
British Columbia, Canada will match EISA - - January 1, 2011
Natural Resources Canada (NRCan) proposed change for all of Canada.
Expect decision after April 20, 2009.
